SPRING BUMPER FOR MOTOR VEHICLES.

Application led September 1, 19 1. Serial No. 585,591.

To all whom 'it 'may C071 cern Y Be it known that I, VLLLIAM (i. (fox, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in a Spring Bumper for Motor Vehicles, of which the following is a specification.

My invention rela-tes to an improvement in a spring bumper for motor-vehicles, and my general object is to provide a wide faced bumper of simple form and pleasing appearance in which the end portions` are sep-.irate sections made' of flat spring bars bent to provide a pair of spaced arms adapted to facilitate attachment thereof to the motor vehicle frame and also doubled edgewise to provide round ends and parallel horizontal impact faces adapted to permit a middle or main impact section. ireferably composed of a plural number ol spring hars, to be connected' at their opposite ends to said end sections as a continuation' of said parallel impact faces.

In the 'annexed drawings Fig. 1 is a horizontal plan of my improved bumper mounted. on the front end of a motor vehicle which is shown in dotted lines, and Fig. 2 is a front view of the saine parts. Fig. 3 is a plan view corresponding to Fig, 1, but showing the middle impact bars removed. Fig. 4 is a perspective view of one of the middle or main impact bars. l* Ig.`5 is a perspective view of one of the bumper end sections. Fig. G is a side view iii dotted linceY of thi` front end ot' a motor vehicle and a, vertical f section ol the bumper on liuc (i-(i ot l* Ig. l. Fig. 7 is an enlarged vertical section on liuc 7 7 of lig. 2 showing au anti-rattling and .spacing device clamped bctwceii the two main impact bars. C

Vln general the chassis fi'aiucs of motor vchicles comprise sidc incinbcis 2 having their front ends 3 curved doiviiivardl)Y and i'ccesscd at their cxtieiiiitics to reccivc the ter- Iiiinal eyes of the t'iont suspension springs` 4 of the vehicle. A shackle holt 5 is uscd to sci-ure the t'i'ont eye ol' ciic'li spring to thi` perforated cud of cach side member 2. This bolt is at a lower elevation than thc straight part ol' thc sidc members Q aud this relationship of parts is utilized in thc present de vice 1o promote thc attachment of a separati 'liuiiipcr section to cach side iiicmher :L using shackle bolts 5 and its uut (i and au other bolt 7 or equivalent means to support the saine. Thus, each end section A consists of a Ushaped member made of a fiat springsteel bar bent edgewise. to provide a fiat bow end 8 and two Hat impact portions9 and 10, respectively, lyingr in the same vertical plane and extending parallel with each other horizontally for a substantial distance from the rounded end 8 before being bent rearwardly in the flat on` curved and straight lines to` provide two parallel supporting arms 11 and 12, respectively, one above the other, each arm having a perforation or boltopening 13 near its extremity. The upper arm 11 is relatively longer than lower ann 12 and spaced apart horizontall and vertically therefrom to permit it to e attached'by a suitable bolt 7 to the outer side of the ciirvedpnd of frame member 2. The lower arm 12 is curved in greater degree 'than the upper arm to place it on the inside of the curved end of the frame where it may be fastened rigidly iii place by shackleb bolt 5 and nut 6, see Figs. 1 and 3, and by refe-I'- riiig to Fig. G of the drawings it will be seen that these two arms extend forwardly on parallel lines and place the two impact faces 9 and 10 iii the same Vertical plane.'V The end sections AAA are exactly alike except that` they extend to the. left and right opposite the tivo front wheels and wheel fenders of the vehicle when attached to the frame as described. and the bow ends of these sections may be curved rearwardly more or less 4to delcct `striking objects and to give the bumper a moi-i` pleasing appearance.

Tin` middle section B comprises two straight spring-steel bars l5 and `1G having* one or more square bolt holes 17 iii their opposite endsl which are adapted to register with ii like number of rouiid bolt holes 18 iii thofrout impact portions 9 and 10 of the end sections and siii able carriage bolts 19 may lic used to detachably iuiite the parts together. 'The preferred way is tol `fasten thc two main impact hars `15 and 16-in paralle] alignment, the uppeisbar 15 being used to tic and connect the upper aiius 11y of the 'two cud .sections together. and the lower ance of an elongated loop viewed from the front ns shown in Fig. 2, although actually having two supporting arms behind the upper har 15 und still another pnir oit sluiportin arms behind the lower bnr i6,

n Fivs. 2 and 7 I show en ornamental disk 2O liavin a pair of channeled ribs Qi at its rear Siae, which extend through the gap or space between the upper :uid lower bars l5 'and 16 und Serve to Seul und hold the heed 22 of u short holt 23 lmving i nut 24 and lock washer 25 adapted lo fasten :L clip member 2G tightly against the rein: VPrice of the two bers. The dish 20 is Sepurulilc from the holt to permit different kinds of ornamental disks to be clamped lo the here, and while this device ie not; actually essential to the bumper it rrves to prevent independent vibration und rattle oiz the two hurra especially if the here nre thin :nul easily flexed.
